Experiment 1 - Feedback

What it meant by the definition a flip-flop or latch is a
"bistable multivibrator
that can assume and store two stable states"?
First, you examine how a logic gate can store a value.
For this you need the concept of feedback.

OR gate with feedback.

Consider again an OR gate.
In the diagram shown the resultQ
is connected to the input of the same gate.
This is called feedback.

Initially, this logical circuit behaves quite normal...

If A= 0, then Q = 0 if,
and only if the value of Q
had already been 0.
